Blender 2.8 and Google Earth Studio (GES) 3D camera integration/import
I actually just solved this problem a few seconds ago for myself after I found AE2Blend: 

https://blendermarket.com/products/ae2blend
($10)

After installing the add-on in blender, I ran the script from Google Earth Studio inside AE and then literally copied and pasted the keyframes into Blender.  Couldn't be easier.

Only issue I'm facing right now is that I animated the Camera Target in GES and that effs up your camera in AE, so I'm currently looking for a solution for this before I have to reanimate.

Good luck!
